The quality of the spring is mainly considered from the following aspects:
The first is its airtightness. If the airtightness of the stainless steel gas spring is not good, there will be oil leakage and air leakage during use;
The second is the accuracy, such as the gas spring that requires 500N; the third is the service life, and its service life is calculated by the number of times it can be fully retracted;
The last is the force value change during the stroke. Ideally, the force value of the gas spring should remain unchanged throughout the stroke. However, due to design and processing factors, the force value of the gas spring during the stroke inevitably changes. The magnitude of its change is an important criterion for measuring the quality of a gas spring. The smaller the magnitude of the change, the better the quality of the gas spring, and vice versa.
